Our intrepid political reporter DAVID BERNSTEIN is micro-blogging the Brown-Coakley campaign as we head into the final 72 hours. Follow Bernstein on Twitter to get the latest. Among his updates recently:

With less than a week to go, the big guns are coming out. Just now: the President releases a new internetty fireside chat to stir up volunteers and turnout.

And tomorrow afternoon, Coakley brings out the biggest gun, Bill Clinton, for a rally with Martha and John Le Kerry at the Fairmont Copley Plaza from 2-4 pm.
